One important reason is that gcc 4.8.1 sometimes crashes:

  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60436

Another reason is that preprocessing assembly files unnecessarily
slows down compilation.

While -O1 and -O2 both include -globalopt, the order in which the passes are
run means that aliases aren't resolved which then causes llc to fall over.

When using TemplateHaskell and -prof, we *do not* want -dynamic-too, because
we're going to *expect* that you compiled the vanilla/dyn way already,
and are compiling profiling the second time (i.e. so GHCi can just load
the normal, non-profiled object files.)
Signed-off-by: Austin Seipp <austin@well-typed.com>

On FreeBSD, /usr/lib has to be added to the library path on linking when
libthr is needed but -nostdlib is used (which is the case when the -prof
and -threaded flags are combined).

This fixes a large majority of the testsuite failures on Mavericks with
Clang.

The -u option must be placed before libraries which define the necessary
symbols.

As Simon pointed out, we should only enable -dynamic-too in the template
haskell case if GHC is dynamic and we're not already compiling in the
dyn way (the dyn way will be switched on by -dynamic-too later in the
pipeline anyway - see pipeLoop)

When compiling a set of modules under --make, we need to check if the
module graph has TemplateHaskell enabled. If it does, then we need to
switch on -dynamic-too for GHCi, so that the linker can properly find
the right dynamic object files.

This includes both executables (by correcly setting the rpath to the
topDir) and libffi, and GHC itself, so that everything works with no
build tree.

This sets the SSE "version" to 1.0.

This commit exposes GHC's internal compiler pipeline through a `Hooks`
module in the GHC API. It currently allows you to hook:

 * Foreign import/exports declarations
 * The frontend up to type checking
 * The one shot compilation mode
 * Core compilation, and the module iface
 * Linking and the phases in DriverPhases.hs
 * Quasiquotation

iOS has some particular constraints about how applications can be built:

 * We must generate a static library (.a) since XCode does the final
   link.
 * We need to carefully give the right set of arguments to libtool in
   the case we're generating an archive.
 * Dynamic linking isn't supported.
 * It can only be done on OS X.

This patch cleans up all of the above. We add a new flag `-staticlib`
(only supported on Darwin) that allows us to produce archive files using
libtool, and a -pgmlibtool flag to control which 'libtool' executable to
use.

This fixes #8127. I believe this is the last piece missing from the iOS
cross compiler.

In 1e2b3780 I changed the option
ordering for C compilations.  A side effect was that -optc options
came before the automatic -O we were adding, which made it so that the
-debug RTS was getting optimised when it shouldn't have been.

Perhaps we shouldn't have automatic -O options added to C
compilations.  But that might cause problems for build systems that
are relying on the current behaviour, so I've made a minor change
instead: now C optimisation level == Haskell optimisation level.

When cross compiling to iOS, we generate archive files which are linked
into the final executable. We already *did* generate archive files -
just with the wrong suffix.

Fixes #8125.

This pass is pretty cheap and eliminates the aliases generated by the LLVM
backend. This in turn is required for dynamic linking to work correctly,
as LLVM fails to properly attribute calls to aliased addresses.

Clang doesn't like whitespace between macro and arguments.
Signed-off-by: Austin Seipp <aseipp@pobox.com>

This is needed because Clang is very strict about C99 macro rules, which
dictate that '#' in a body must have a token immediately following it for
string-ification. In practice we break this all the time, because we do
very weird stuff like:

    #define FOOBAR(xyz) \
    {-# SOME PRAGMA #-} \
    baz :: (xyz) \
    baz = ...

where the leading '#' in in the macro body clearly breaks this rule.

Now these are always added by the run<blah> functions in SysTools, so
we never miss any out.  Several cleanups resulted.

On iOS, binaries are really static libraries, so we don't want to use
flags like -lm when linking them.

We now just pass the filename as an argument

We now just pass the output filename as an argument instead

The output location needs to be different for the vanilla and dynamic
ways when doing -dynamic-too. Fixes dynamicToo003.

Without it, when linking the split objects for Language.Haskell.TH.Syntax,
the commandline was too long when listing all the files directly.
